An education specialist says charter school pupils could cost the Government more than twice as much as pupils in state schools.
The Government intends to have charter schools open by the start of the next school year and has announced they will get more money than state schools but less access to centrally provided support.
Massey University education professor John O'Neill has examined funding models proposed for charter schools and says the schools could receive as much as double the funding per student as the public institutions.
Professor O'Neill says that money would be better spent on existing schools which will suffer having to compete with new charter schools in the area.
